Individual contributions, accountability and exposure of athletes are fundamentally different in individual and team sports. It is generally known that the choice of sport and personality traits are in mutual interaction. Previous research on the issue of differences in personality traits between team and individual athletes, for which due to the substantial qualitative differences between these two groups of sports to be expected to exist, resulted in contradictory findings. Considering the stated goal of this research was to examine and compare personality traits and pre-competititon anxiety in athletes of individual and team sports. The study involved 240 athletes (121 individual and 119 team sports; 130 young men and 110 girls). Participants filled out questionnaires which included personality traits (HEXACO questionnaire), perfectionism, and pre-competition anxiety. Results showed that individual and team athletes differ only on the dimension of extraversion whereby athletes of team sports achieved higher results. On the dimensions of honesty/humility, emotionality, agreeableness, conscientiousness and openness, no significant differences have been identified as well as on the dimensions of perfectionism. Individual athletes achieved higher results on the scales of cognitive and somatic anxiety, while on the level of confidence they did not differ. Further analysis showed a positive correlation of perfectionism with cognitive and somatic anxiety and negative correlation with selfconfidence. There was also a significant positive correlation between cognitive and somatic anxiety, while both dimensions were negatively related to self-confidence. In conclusion, team athletes are more extroverted and experience less cognitive and somatic anxiety than the individual athletes, which can have practical implications for psychological preparation and athlete training.
